This invention relates to a steering attach ment for tractors, of the class adapted toaccomplish steering a tractor when plowing and listing by use of a guide adapted to travel in a furrow.

One of the objects of the invention is to provide a shoe for the attachment at the front of the tractor which will be automati cally maintained parallel with the line of traction so that the supporting-bar for the guide will be maintained approximately at right-angles to the furrow. I

' Another object is'to provide a steering attachment of such construction that the trac 5 tor may travel at selected distances from the furrow, the distance of the shoe from the furrow not being changed.

Still another object is to provide a standard for the steering attachment for use when supporting the guides when turning about at the end of a field or when moving the guides to the right or left side of the line of traction.

' Still another object is to provide an at tachment of the class described which will resist side stresses directedthereto while cul-. tivating ground which is inclined transverse ly to the line of travel.

The invention includes a steering attachment adapted to be used for listing and genplowing. I

With the foregoing objects inview and others to be mentioned hereinafter, the invention presents a new anduseful construction,

85 combination and arrangement of parts as described and claimed and as illustrated in the accompanying drawings, it being understood that changes may be made in form, size, proportion of parts and minor details, said changes being within the scope of the invention as claimed.

Fig. 2 is a View of the attachment in side' elevation, a part of a tractor, in section, being shown. Fig. 3 is a plan view of the attachment arranged for listing. Fig. 4 is a side view of the parts shown in Fig. 3. Figs- 5,

Referring now to the drawings for a. more particular description, the invention is shown and described in connection with the front wheels 10, axle 11, the spindle-bars. l2 and the coupling-rod 13 whichconnects the two spindle-bars one with the other, these being well known parts hereinafter called the steering mechanism of the tractor; f

extends forwardly. of' the tra'ctorfor use with other parts to be described. it may have any suitable connection with the steering mechanism of the tractor, the connection" shown herein being a bolt 15 (Fig.1) which pivotally connectstherear endo'f said. arm 14 with the coupling-rod'13." l

I provide a carrier-beam 16 which extends forwardly from the tractor, and provide a coupling structure for. connecting'the' rear end of said carrier with the front axle 11, said coupling. structure being of such arrange'. ment that the carrier-beam may have .swing-. ing movements horizontally-and vertically relative to the axle. While. any suitable means may be provided to permit these movements, the coupling structure preferably consists of'a vertical pivot or bolt 17 (Figs. 1, 5) which is-mounted in a vertical socket-18 which is secured to'a horizontal supporting-plate 19.: Brackets :20. are secured to the axle 11 by means ofa pair of U-bolts 21. The plate 19 is of angular form and, as clearly shown in F 1, is bent to, provide end-portions disposed .at right-angles to the body of said plate, and byfm'eans ofhorizontal bolts 22 which engage in said-brackets and end-portions of the plate 19, said plate will be mounted to-permit movements of the carrier-beam in'vertical planes, the mounting of the verr i as Numeral 14 indicates a steering-arm which tical bolts 17 permitting the carrier-'beamtoswing in horizontal planes.

While I. have shown and? described achainififi for the uses mentioned it isobvious that a metallic; bar. or rod could be substitutedrtherefor and operation would be practically the same. a 1 v In operationc no attentionfloifa a driver is needed. for the tractor except: whenWturnirrg about at the endrof a field; If the furrow 35 lea dsvlin a straight: line the line: oiiitraction will correspond thereto and the carrier-beam I will I have no horizontal swinging movement. However, if the. furrow s has ,aacurvature the i carrienbeam 16 will have a hori z'ontalswing.

ing' movement and this movement will be communicated to the steering-arm 14' on account. of the action of. thewcontrolbar 38 whichis' pivotally connected at its respective ends withr said beam: 16 and-arm 14o.

For instance, ifthe furrow 35 has aycuirvas turc tothe right? of the direction: of travel oii :the tractor it is obvious thatfthe beam 16 willswing horizontally towardthe ofi side e and the control-bar '381willf be: moved lon'gl tudinalily in the same direction to cause! an of the steering; arm 14, amid-this last named movementiwill'cause the tractor to move on a line conforming toithe v3 curvature ofwth'e furrow. Also itwill benoted that regardlessi oflthe' dfinee'; of curvature oft-a furrow the shoewillbe maintained parallelwith the-line guide-member 34 will normally remainin-tho;

mally;"=be disposed at, to the, u r w-w I e The bar 27 of the shoe is pivotally mounted, as indicated at 39 upon the front end of the equalizing-bar 30 which operates as a fulcrum, and any horizontal swinging movementof the shoe will be coincidently communicated to the steering-arm 14 and to the steering mechanism of the tractor.

In operation, the carrier-beam 16 and equalizing-bar 30 may be disposed in angular relation to the line of traction, but according to the present construction, the shoe will at all times be maintained parallel with the line of traction, and this feature is of great advantage since thesupporting-bar 82 during operation, will be disposed approximately at right-angles to the furrow so that there will be no tendency for the guide-member to leave the furrow while the tractor is moving.

The control-bar 38 operates to advantage for many purposes as will be seen. When operating in rough ground, either plowing or listing, this bar tends to resist side stresses directed to the shoe, the equalizing-bar and carrier-beam, for the reason that it is mounted on the steering-arm, and since the latter is pivotally mounted between its ends as in dicated at 40, stresses directed to either side of these parts willbe resisted.

In operation, itis often desirable to have the tractor move very close to the furrow 35 especially if the ground to be plowed or listed is inclined transversely to the-line of traction, and the invention includes such a mounting of the steering-arm that this may be accomplished. By referring to Fig. 1 of the 'drawingsit will be seen that the carrierbeam 16, equalizing-bar30 and steering-arm 124' are'disposed approximately parallel with the line of traction and that the control-bar 38 is provided with notches 41. The steering-arm, at its end, is provided with a downwardly projecting pin 42 adapted to engage in any selected notch 41, and to accomplish this adjustment, a pull-rope43 is provided.

By use of the pulFrope the bar 88 may be swung rearwardly against the force of a spring 44 so that the pin or projection 42 may engage in any selected notch of said bar 38.

VVhenit is desired that the tractor shall move with its off wheel close to the furrow the pin42 is disposed in a notch nearer to thc free end of the bar 38, the result being that the steering mechanism of'the tractor will be changed to cause the tractor, during its movements, to be disposed closel adjacent to the furrow 35, and during the forward 1 travel of the tractor the carrier-beam 16' and equalizing'-ba rv 30 will remain parallel with reference to each other but they will'swing and will be inclined toward the near? side of the line of traction, that is tosay, the trad tor and rear ends of members 16 and 30 will,

be disposed closer to:the furrow than before and the front ends-of said members 16 and 30 will be-disposed the same distance from the furrow as before.

The adjustments just described for the steering-arm 14 proves to be of importance since tractors are now in general use for plowing and listing ground on hillsides and in valleys and rough and undulating ground, and in such instances these adjustments are always made to cause the tractor to travel at a selected distance from the furrow.

It will be noted that when an adjustment has been made as last described the shoe 26 will be disposed parallel with the line of traction, this feature being of importance so that the brace-member or chain 36, in connection with said shoe will maintain the supporting-bar 32 approximately at rightangles to the line of traction.

it will be seen that the function discharged by the spring 44 is to cause a constant pressure of the control-bar 38 so that it will be pressed forwardly against .the pin or projection 42 of the steering-arm. This is simply a ma'tterof convenience and I may dispense with this spring 44 and. notches 41, if desired, and provide other equivalent means. While I prefer the construction as shown and described I do not wish to be understood as limiting myself in this respect. Also while I- have shown the mounting of'the rear end of the arm 27, and I may substitute other 7 means to operate as a fulcrum. Also I may dispense with the use of the bar 28 since it operates simply as a brace to reinforce the arm 27. y

l/Vhen turning about at the end of a field or when driving upon a highway, the guide or discs 34 must be removed from the furrow, andtherefore I provide means for elevating itand for maintaining it in its elevated position. For these purposes I provide a standard 45 which projects upwardly from the rear end of the shoe and is secured thereto. This standard may be of any suit able construction and may have any suitable height, and asbest shown in Fig. 20f the drawings it, preferably, has a rearward in clination so that it will not be obtrusive when the supporting-bar 32 and its discs 84 have been swung upwardly.

Upon thetop of'the standard is an inclined head-piece or'plate 46 provided with a V- shaped notch 47 and upon the plate "46 is mounted a pair of rollers or pulleys '48. I provide a chain 49 which is secured at one of its ends to the supportingbar, the opposite end of said chain being provided, preferably, with a rope or cable 50, and an operator, b use of the rope, may cause thesupportingar and discs to swing upwardly, the T chain moving between the pulleys LS, and

one of the links of the chain being caught in: the? \lu-sha ped notch 4W, whichwoperates to maintain'theasupporting-b-ar 32 and discs in. the elevated position mentioned; To releasew the chain from'the notch,an operatorshalses the rope in a: well known manner to cause the chain to spring upwardly from theV-shaped notch and permits thesnpponting-bar 32 together with its discs; to' swing ,downwardlyf While I have shown and describedfla vpair of pulleys 48, they are simply for the purpose of controlling; the direction of movement of the use of the pulleys mentioned.
